Patented July 10, 1906.

Application filed September 11, 1905. Seri'aL No. 278,053.

To all whom,v it mar concern:

Be it known that I, THOMAS MoOoaMIoK, a citizen of the United States,residing at Mount Pleasant, in'the county of VlZestmorecapable ofholding a comparatively great quantity of fuel and maintaining it inharmless condition, vaporizing meohanism'being also provided, whichautomatically returns all surplus or unvaporized fuel takenfrom thereservoir back to the same.

The referred embodiment of the invention is illustrated in theaccompanying draw inns, wherein- V igure 1 is a vertical longitudinalsectional view through the carburetor. Fig. 2- is a horizontal sectionalviewtherethrough, and Fig. 3 is a vertical cross-sectional view.

Similar reference-numerals designate corresponding parts in all thefigures of the drawmgs. a In the embodiment illustrated an oblong casing4 is employed, preferably, though not necessarily, constructed of sheetmetal and forms a mixing-chamber 15, the bottom ofsaid chamber beingperforated, as shown at i 16, and bein spaced from the partition 5 ,:theportion of the partition beneath the perfo rated bottom 16 also beingperforated, as

shown at 17 A plurality of air conduits or pipes are provided withupright inlet termi-r.

nals 18, that 1pass through the partition 5 and telescope Wit nipples19, carried by the bot- A fillingw tom ofth'e boxing The pipes are thusin communication with-the lair-compartment 9; Themain portions 20 of thepipes or conduits extend in a substantia-lly horizontal directionwithinthereservoir and areperforated, as shown at 21:.- The said reservoir iscom pletely-filled with suitable absorbent packing ;material, such aswaste or asbestos, (shown at 22,). the material completely surroundingtheperforated-portions of the pipes. S'aid pipes also terminate inupstanding discharge ends 23', that project above the partition 5, andinclude discharge-nozzle elbows 24:, that project into themixing-chamber 15, being thus located above the perforated partition .5;I A suotion-pipe25 is connected to the casingland has its Inlet end incommunication with the separating ohamber 6'. This suc tion-pipe isadapted to be connected to an explosive-engineor other device forcreating a current of air through the pipes. To=supply thecarburetor-with fuel, it is only necessary to remove-the plug 13 andpour fuel into the air-compartment 9, whereupon said fuel will flow intothe air conduits or pipes and, escaping through the erforations thereof,will be I thoroughly absor ed by the packing.

In oeration a current of air is created throu the mechanism by the meansattache to the suction-pipe 25. This will cause a partial vacuum withinthe casing, which will be relieved by'the opening of the check-valve1 1. The air thus passing through the compartment 9 will enter andtraverse the air conduits or pipes, taking up and vaporizing the fluidtherein and finally escaping into t e mixing-chamber 15. From thenceit'will pass through the perforated bottom into the separating-chamber 6and to the suc- .tion-pipe 25. If an abnormal amount of fuel iscollected in the pipes, 'the surplus or unvaporized portion will bedrawn therefrom and delivered into the mixing-chamber, from rated bottomonto the perforated partition 5, constituting a top fo'rthe reservoir.Through this top or partition it will find its way back into thereservoir, where. it will be absorbed by the packing.

It: will be apparent that this structure is an exceedingly-simple one,and experience has demonstrated that it will properly and thorv whence-.,it will gravitate through the perfo- ,oughly vaporizefuel in thereservoir. While 1 a said reservoir will contain a considerable quantityof fuel, it will be evident that the same will be maintained in acomparatively harmless condition, as it is absorbed by the packing.Furthermore, any portion of the fuel that collects in the pipes will beimmediately withdrawn therefrom when the engine is operated and returnedto the packing, so that no body of fluid of any great amount willcollect in the apparatus.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described invention will be apparent tothose skilled in the art without further description, and it will beunderstood that various changes in the size, shape, proportion, andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a carbureter, the combination with a casing, of a perforatedpartition located there- 1n, said partition subdividing the interior ofthe casing into a lower reservoir and an upper separating-chamber, anair-pipe having a perforated portion extending through the reservoir,said pipe extending into the separating-chamber and terminating thereinabove the partition, and a delivery-pipe communicating with theseparating-chamber.

2. In a carbureter, the combination witha casing, of a (perforatedpartition located therein and sub ividin'g the casing into a lowerreservoir, and an upper separating-chamber, an air-pipe having asubstantially horizontal perforated portion extending through thereservoir above the bottom thereof, said pipe having an upturned endportion that extends through the partition and terminates over the samein the sep arating-chamber, and a delivery-pipe communicating with theseparating-chamber.

3. In a carbureter, the combination with a casing, of aperforatedpartition located therein and subdividing the same into a lowerreservoir, and an upper separating chamber, an air-pipe having adownwardlyextending inlet from the top of the casing, asubstantiallyhorizontal perforated portion extending through the reservoir, and anupturned end portion that extends through the partition and terminatesover the same in the separating chamber, said upturned end portion abovethe partition being imperforate, and a delivery-pipe communicating withthe separating-chamber.

4. In a carbureter, the combination with a casing, of a partitionlocated therein and subdividing the same into a lower reservoir and anupper separating-chamber, an air-pipe having a perforate portionextending through the reservoir, said pipe extending into theseparating-chamber, a mixing-chamber located in the separating-chamberand having 5. In a carbureter, a reservoir for fuel having a perforatedtop, an absorbent packing in the reservoir below the top, an air-conduitextending through the reservoir, through the top and terminating oversaid top, said conduit having a portion located in the reservoir,surrounded by the packing and perforated, and means communicating withthe space between the top and terminal of the conduit to cause adownward draft from the latter and to effect a downward discharge ofunvaporized fuel onto the top. 6. In a carbureter, the combination witha reservoir having an open top, of a mixingchamber located above thereservoirand having an open bottom, a perforated air-conduit extendingthrough the reservoir and discharging into the mixing-chamber, and asuction-pipe having communication with the space between the open topand bottom of the reservoir and chamber to cause a downdraft through theopen bottom of the mixingchamber.

7. In a carbureter, the combination with a reservoir having a perforatedtop, of a mixing-chamber located above the same and having a perforatedbottom disposed over and in spaced relation to the top of the reservoir, and an air-conduit having a perforated portionextending throughthe reservoir, said conduit extending across the mixing-chamber andhaving an outlet communicating with said mixing-chamber.
